Why should I choose a 30-Gallon Aquarium?

A 30-gallon aquarium can be a great choice for someone who wants to dive into aquascaping but isn’t willing to start small. Luckily, this is a reasonable-sized tank, large enough to not fall into the smaller tank category and it is not a very man-sized tank either.

A 30-gallon fish tank also makes a great choice for someone who is very fond of aquariums. Someone who is passionate about being an aquarist and wants to add another tank to his collection. This sort of person would normally want to add another species or develop a different ecosystem and there’s no better way to do that than by bringing a brand-new aquarium to the table.

It also serves as a great stairway for someone who is looking to grow his way into being an aquarist. It’s smaller, doesn’t require a bulky stand, wouldn’t need loads of cleaning, yet still be large enough to accommodate all your aquarium-level species.

So, whether you are a first-timer, an experienced aquarist, or a seasonal one, a 30-gallon fish tank can be a great choice for anyone under the right circumstances.

How do I choose the best 30-Gallon Fish Tank?

To help you make a better decision during your purchase, remember to include the following factors in your pre-purchase checklist:


The two common materials for a 30-gallon aquarium are glass and acrylic. A glass aquarium will always be more prone to breakage. On the contrary, an acrylic tank is more sturdy, twice as more durable than glass. While a glass tank is hyaline, an acrylic tank is stronger. The choice is yours.


Defining your budget will help you get more in less amount. For instance, if budget is not an issue, you can buy a complete, equipped tank and it will save you effort and time.

If you are operating under a budget and you want to have a 30 gallon tank, that’s when you go for something affordable while scoring as much accessories as you can.


Determine where you want to set up the tank in your house. If you consider placement beforehand, it will help you choose a design that will complement your interior décor. Proper placement/design will always help you avoid any issues in the future.


The standard 30-gallon tank comes in a 36 ¼ x 12 5/8 x 16 ¾ size. Variations in shape and due to the purpose of each tank, this size is subjected to vary.


There are a couple of fish tanks out there. Coldwater freshwater tank, tropical freshwater tank, tropical marine tank, brackish tank, reef tank, coldwater marine tank, etc. are some top examples. Each fish will require its own vibrant living environment. Many a time, you will find aquariums on sale for their specialization in one of the above types. So, bear that in mind and you might land a great deal for yourself.


Sometimes, your aquarium will come with a top that holds a colorful set of LEDs – which is great. However, some people prefer setting up their own lighting, to help them grow live plants. Keep this in mind so you can buy accordingly.

How to set up a 30-Gallon Fish Tank – Setup Idea

First and foremost, you will need a nice substrate layer at the bottom of your tank. Here are a few ideas we have for you in this regard:

  1. Wash the gravel/substrate well and remove any pointy stones.
  2. Make sure all the equipment you have is ready to use and suitable.
  3. Pick a good place for your tank
  4. Place the live plants and anchor them well
  5. Set up all the decorations
  6. Set up all the necessary equipment
  7. Once everything is in place, slowly add water to your tank
  8. Remember to add any necessary chemicals, salt, purifiers to your tank
  9. Turn the equipment on and leave it on for some time
  10. Check the nitrate and ammonia levels – they’ll peak once and then they’ll fall to zero, that’s when it’ll be safe for you to add the fish.
  11. When adding fish to the tank, make them slowly adjust to your tank’s water. Add the tank water into the fish bag slowly (take hours) and then get the fish into the tank.

These fish are guaranteed to feel very comfortable in a basin that is 28 – 34 inches in length. Hence, a 30-gallon tank would qualify as a fine home.
